摘要
The problem of crack growth along the interface of two immiscible homopolymers is studied where the interface is strengthened by the addition of a small amount of diblock copolymer. A micromechanical model of the interface is proposed and a time-dependent Dugdale-Barenblatt model based on this model is used to predict the fracture toughness of the interface as a function of the applied loading, the crack growth rate and the underlying interface properties.
